if there is a token in a fork do not signal it. The child tokens are created in the jbpm fork 'implementation' as you might have expected. How to get the childtokens? Have you had a look at the api? (using an IDE with code completion also works ;-)) Tokens have names related to the path
I was aware of the path to the node, but it just did not strike me I could use it for my purpose. Thanks again!
